how long did it take for your ears to adjust since your other speakers were Polks because recently having just gone through this myself, I wasn't so sure at first when I got my new speakers home. The the one thing about a neutral sounding speaker is the somewhat lack of detail at first, but when you actually listen its all there except its not fatiguing and puts a smile on your face.
Congrats on the new speakers, Bill
BTW Jacksmyname has the s10 and 12 and very happy with both.
